Karaer A, Doğan B, Günal S, et al. - Researchers conducted a prospective cohort study with the aim to determine the influence of vaginal microbiota on pregnancy outcomes in women undergoing assisted reproduction. From 223 women undergoing ART treatment, vaginal samples were obtained from the posterior fornix prior to embryo transfer. Women who failed to become pregnant showed greater relative abundance of Streptococcus (7.81%) and Gardnerella (9.40%). Linear discriminant analysis (LDA) validated that Streptococcus has the greatest contribution to the distinction between women who became pregnant and those who failed to become pregnant.
